ISL59832	June 2008

Dual Channel, Single Supply Video Reconstruction Filter with Charge Pump

The ISL59832 is a dual channel, single supply video driver with reconstruction filter and charge pump. It is designed to drive SDTV displays with S-Video (Y/C) signals. It operates on a single supply (3.0V to 3.6V) and generates its own negative supply (-1.5V) using a regulated charge pump. Input signals can be AC- or DC-coupled. When AC-coupled, the sync tip clamp sets the blank level to ground at the output of Channel 1 thus ensuring that the sync-tip voltage level is set to approximately -300mV at the back-termination resistor of a standard video load. Channel 1 also has a sync detector whose output is available at SYNC_OUT pin. In a typical application where the luma is connected to Channel 1, and chrominance is connected to Channel 2, SYNC_IN is connected to SYNC_OUT thus providing timing to Channel 2. Channel 2 has a keyed clamp which sets the output to ground when SYNC_IN is driven to the logic high state. The ISL59832 is capable of driving two DC- or AC-coupled standard video loads. The ISL59832 features a 4th order Butterworth reconstruction filter that provides a 9MHz nominal -3dB frequency and 40dB of attenuation at 27MHz. Nominal operational current is 31mA. When powered down, the device draws 1μA maximum supply current. The ISL59832 is available in 16 Ld TQFN package. More

It is designed to operate on a single supply (3.0V to 3.6V) and generate its own negative supply (-1.5V) using a regulated charge pump. Input signals to the ISL59834 can be AC- or DC-coupled. When AC-coupled, the backporch clamp sets the blank level to ground at the output. Channels 1 and 3 have a sync detector whose output is available at SYNC_OUTA and SYNC_OUTB, respectively. SYNC_INA and SYNC_INB are inputs that provide timing for Channel 2 and Channel 4, respectively. Channel 2 and Channel 4 have keyed clamps, which set the outputs to ground when SYNC_INA or SYNC_INB are driven to the logic high state. Each of the four outputs are capable of driving two DC or AC-coupled standard video loads. The ISL59834 features a 4th order Butterworth reconstruction filter that provides a 9MHz nominal -3dB frequency and 40dB of attenuation at 27MHz. Nominal operational current is 63mA. When powered down, the device draws 5μA maximum supply current. The ISL59834 is available in a 44 Ld 7x7 QFN package. More
